Here's something I explore frequently. This is a section of the Niagara Escarpment in Central Wisconsin. It consists of Silurian aged sediments, predominantly dolomite and limestone formations. It extends for hundreds of miles and can be found as far from here as New York. This area is locally known as The Ledge, and is as treacherous as it is beautiful. People have actually died here, drawn in by The Ledge, only to stumble over. Caution is advised if visiting. I have navigated and explored this labyrinth like formation my entire life. However some depths I dare not travel to. This ladder pictured above, is the only human made structure I've found here. I have yet to see where it goes. If you ever run through Wisconsin, I highly recommend you look at our ancient attractions. The Ledge represents only the tip of the iceberg here in Wisconsin.

I’ve just bought this book with some birthday vouchers I was given early in the year. The book is Strata, William Smiths Geological Maps. The book is absolutely gorgeous. A real coffee table book giving the history of William Smiths career, his production of the first geological maps and of course his fossil collecting that went with it. Here is a link to the book on Amazon. https://www.amazon.co.uk/STRATA-William-Smiths-Geological-Maps/dp/0500252475/ref=mp_s_a_1_1?crid=1AYFHUQ9YTN8H&keywords=strata+book&qid=1664115356&sprefix=strata+book%2Caps%2C73&sr=8-1 I’ve also added a few pictures below to give you an idea of the quality and size of the book. Well worth the money, especially if you’re interested in the history of geology.

Hello, forum! I recently came back from a long polar summer trip in Iceland. I was not ready for the hot air in Texas but luckily I brought some rain back with me to help with the drought conditions in DFW! I got to stay there getting to learn about my family’s culture. Homebase was in Hveragerði so I got to go to Vík a lot! I also stayed in the capital for a little bit which was fun! During my adventure I got to see glaciers, felt mini earthquakes/tremors, went to many hot springs, went to all the popular waterfalls, climbed a few volcanos. As long as I was there however I didn’t get to see the whole country! I only got to see the south, west, and some of the northwest fjord areas. Bull-Giant territories. Next time Eagle-Dragon territories for sure. *I didnt get to see the new eruption near Blue Lagoon unfortunately, I just missed it! Maybe the country is mad I left. If you’ve never been, there are almost no fossils to find there but some amazing stones and rock formations! Its a very rocky, bumpy, volcanic island. Rockslides happen, fog happens, volcanos are normal and eruptions can happen. It’s illegal to take anything from nature home- except when I went to the lava show in Vík where I got a sand necklace and glass fibers they made called “witches hair”. Most beautiful country I’ve ever been too! Very happy to know its second home and that the region is part of my life. If you ever visit there please be respectful of the nature. Best part of temporarily living in Iceland is: Fresh air, fresh local seafood, fresh dairy made next door in Selfoss, local made products, dramatic landscapes, midnight sun was a cool experience, black sand/dark rocks, cooking bread and boiling eggs in the hot springs daily (sulphur smell!), horsies are the perfect size for me, clean water, mild temperatures in late winter-summer, the names for landmarks and cities are a literal translations of a combination of nouns, and best of all it’s a “green” country that runs on geothermal so never-ending hot water in shower! (no it did not smell like eggs.) I love that its NEVER allowed to drive or park offroad to protect the nature. It’s also illegal to disturb large stacked stones usually seen in the country (ancient settler path markers!) however I saw people in the capital coastline and beach do it with tiny stones which is fine- just don't do it on the grasslands. Iceland was overall the best experience of my life! If you love geology- this is a great place to visit. Rock pictures! *It wouldn’t let me upload more photos but here are some attachments! Bonus pic of fox at a shelter, puffin photo through my binoculars, abandoned wild puffin burrows I found. Also-eider ducks! I have about a thousand pictures of food and animals as well.

Hello Everyone. My grandaughter is in 4-H Geology and we found this specimen in Southwest Kansas. We have no idea what it is or how to label it for her exhibit box. Any help you could give us would be greatly appreciated. Thank you!

I have been on a few geology forums recently looking to post some pictures for ID help. Some of the other posters on those sites received replies with snark and sarcasm. To be fair my experience is just a small snapshot im sure, but I really haven't seen that on this site. Everyone seems helpful and informative so far. Anyone know of a similar geology site that encourages learning? Thank you!

Geomorphology in locations situated away from plate boundaries
IsaacTheFossilMan posted a topic in Geology
I've been doing research, and come to my own conclusion to the following question, but would like peoples input: How does terrain form in locations far away from plate boundaries? Obviously, normal fault dynamics, or, any fault dynamic doesn't affect these locations too much, but, warping and folding of the plates can cause ruptures to appear, leading to volcanic activity, forming and depositing new land. These endogenic processes form an "input" for final terrain form, then exogenic processes take over, consisting of weathering and erosion of all kinds. Hydraulic erosion is a key component in this "output" process, depositing and translating matrix from one location to another. Presumably, this is all it is? Depositing of new material from rivers, rain, and wind, coupled with the buckling of plate crust - shown in the famous Rocky Mountains - and volcanic activity form interesting and varied terrain, even away from faults. Note that volcanic hotspots can form from normal (divergent) faulting, as well as being diverted further away from a reverse (convergent) fault. Isaac -
Hey fossil people... more specifically hey Arizona fossil people. I'm wondering if any of you have run across fossilized horn coral in this state? If you have, tell me about it. I'd love to see examples of what you've found. I"ve found lots of brachiopods and other marine life in Arizona but this is the first time I've found horn coral. The idea that Arizona used to be underwater is fascinating to me. Theyre not the prettiest specimens... but i found them and they're mine! Lol. For those wondering, I found these near Payson Arizona. Same place I've found byrozoans, brachiopods, and crinoids.

Lets hear your best palaeontology puns!
IsaacTheFossilMan posted a topic in Members' News & Diversions
As the title states, lets hear the best puns you've got! I think we all need a bit of laughter these days especially, so lets raise a glass (and hopefully a smile!), and share our best (rock)cracking puns! Puns and jokes accepted from geology and palaeontology! Lets start off with one per person, and to get us all started, something I thought of today! What's a geologist's favourite drink? Gin and tec-tonic! -
Look I found a thing! Usually when I see a rock embedded in another rock I think fossil... however IF this is a fossil I have no idea what it would be. So at this point im thinking maybe its another Xenolith. What are your thoughts? For anyone interested, this was found near Vancouver Canadia.

Chatting with Lizardite about Northern California geology
DPS Ammonite posted a topic in General Fossil Discussion
@lizardite I thought that we should move this interesting reminiscing about northern California geology and paleontology out of the member introduction section so that more people might see it. Continuation from: http://www.thefossilforum.com/index.php?/topic/122442-greetings-from-carlsbad/&tab=comments#comment-1339414 Here is one of my interesting finds from the Bay Area. The most recent palm fossil found in Northern California. I could not convince UC Berkeley to keep it. -
Does anyone have any ideas on what transformations an organism undergoes as it becomes an inclusion? Why do they often become translucent or transparent? Why do they often turn black/brown? Do they polymerize? How do some inclusions retain a lifelike or unaltered appearance? Why do exposed sections of inclusions have a crystalline appearance? I'm surprised that I can't find any meaningful answers to these questions.

I'm assuming this is just geology, but I wanted to make sure. I found it in a seasonal creek bed in south central Missouri, USA. It measures 3 inches by two inches and is a little whiter than the image indicates. Any help is appreciated. Doug

Hello everyone, I am looking to identify an interesting sedimentary formation that I found in the Upper Devonian of Pennsylvania. It was found in an area with many ichnofossils, initially I believed that it was geological in origin and that it was just some interesting structure that the sandstone formed. I asked a few people who are much more knowledgeable on geology than me and got mixed responses, some said it was small scale soft sediment deformation, others thought it may be some kind of ichnofossil. I wanted to ask on here if anyone else has any ideas, geology and ichnology are not things I am that familiar with so I have no idea as to what it may be. Any help is greatly appreciated, Thank you
